[Elecraft] K3 programming commands problem

[Robert Tellefsen]

I'm trying to get some of the K3's functions to respond
to commands from my computer, running TR LOG.
I have the TX antenna switching ok with the AN1 and AN2
commands.  However, I can't find a way to get the RX ANT
command to work.  The programmers reference says that the
the K2's SW commands (SWT and SWH in K3) are not yet
available.  Has anyone found a work around for this?

Thanks and 73
